Answer:
3.47
Step-by-step explanation:
since the third decimal is less than 5 then it doesn't carry over to the 7 thus it remains 7.
When you solve the following equation, solving for the quadratic formula.
The answer is; x=4
Next time pay attention in class.
Answer:
It is mainly used while doing scientific notation. If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100.A quarter is 0.25 dollars so the ratio between 1 dollar and a quarter is 1/0.25(it means the dollar and the quarter which is 0.25 dollars) and that equals =4
Answer: 3
Step-by-step explanation: To solve for A we need to get it by itself by doing the inverse of mulitplication, which is, division. 27/9=3, so a=3.
2x + 3y = 12 (1st)
5x − y = 13 (2nd) ---> y = 5x - 13
Substitute y = 5x - 13 into (1st) equation
2x + 3(5x - 13) = 12
2x + 15x - 39 = 12
17x - 39 = 12
17x = 51
x = 3
substitute x = 7 into y = 5x - 13
y = 5x - 13
y = 5(3) - 13
y = 15 - 13
y = 2
Answer
solution x = 3 and y = 2
